Chainer Chemistry: A Library for Deep Learning in Biology and Chemistry

PyPI GitHub license travis Read the Docs

Chainer Chemistry Overview

Chainer Chemistry is a deep learning framework (based on Chainer) with applications in Biology and Chemistry. It supports various state-of-the-art models (especially GCNN - Graph Convolutional Neural Network) for chemical property prediction.

For more information, please refer to the documentation. Also, a quick introduction to deep learning for molecules and Chainer Chemistry is available here.

Dependencies

Chainer Chemistry depends on the following packages:

These are automatically added to the system when installing the library via the pip command (see Installation). However, the following needs to be installed manually:

Please refer to the RDKit documentation for more information regarding the installation steps.

Note that only the following versions of Chainer Chemistry's dependencies are currently supported:

Chainer Chemistry Chainer RDKit Python
v0.1.0 ~ v0.3.0 v2.0 ~ v3.0 2017.09.3.0 2.7, 3.5, 3.6
v0.4.0 v3.0 ~ v4.0 *1 2017.09.3.0 2.7, 3.5, 3.6
v0.5.0 v3.0 ~ v5.0 *2 2017.09.3.0 2.7, 3.5, 3.6
v0.6.0 v6.0 ~ *3 2017.09.3.0 2.7, 3.5, 3.6
master branch v6.0 ~ *3 2017.09.3.0 2.7, 3.5, 3.6
v0.7.0 release plan v7.0 ~ 2019.03.2.0 3.6, 3.7 *4

[Footnote]

*1: We used FunctionNode in this PR, which is introduced after chainer v3. See this issue for details.

*2: Saliency modules only work after chainer v5.

*3: Chainer v6 is released and ChainerX is newly introduced. In order to support this new feature & API, we are going to break backward compatibility for chainer chemistry v0.6.0 release. See ChainerX Documentation for details.

*4: We are going to drop python 2.x support in the near future.

Installation

Chainer Chemistry can be installed using the pip command, as follows:

pip install chainer-chemistry

Example to install rdkit with conda:

# newer conda version is necessary to install rdkit 2019.03.2.0
conda install -n base conda==4.6.14
conda install -c rdkit rdkit==2019.03.2.0

If you would like to use the latest sources, please checkout the master branch and install with the following commands:

git clone https://github.com/pfnet-research/chainer-chemistry.git
pip install -e chainer-chemistry
